This paper considers three different ways that heritage can be considered fragile—as a reference to the conservation status of the physical heritage, as a concern for the meaning of the heritage, and in terms of threats to the knowledge potentials. It also briefly considers any special conditions that may characterise the threats to heritage in Africa and the consequential challenges to its heritage managers and politicians. On this basis, the experiences of working on one of the first systematic archaeological projects in Cape Verde are used to think about how these challenges are encountered within a specific place but from the viewpoint of foreigners and archaeologists.  相似文献

This paper examines some problematic methodological and ethical issues associated with in‐depth qualitative research with children. The discussion has wider resonance for qualitative studies of young people in ‘rural’ contexts. Particular ethical issues arise when researching with children, which are underpinned by children's relative powerlessness in society. With this in mind, the paper considers substantive strategies to promote ‘empowering research relations’, drawing upon an empirical study with children in primary school spaces. Re‐theorisations of identities and power as fractured, dynamic and contextual, suggest that research is comprised of specific moments or ‘research performances’. It is argued that developing empowering research relations involves negotiating such performances in ways that contest, or transform, dominant societal relations between children and adults. In this paper, I consider some of the specific, embodied performances involved in my research, to expose some of the complexities of power relations and negotiations within space. Bringing to light particular moments emphasises that power relations between children and adults are not reducible to the powerless and the powerful. It is also demonstrated that research performances are influenced and constrained by expectations placed upon adult and child practices in society and institutional spaces, and by researchers' own unconscious reproduction of dominant identities.  相似文献

Hydraulic plasters or mortars prior to the Roman period are rare. Here, we report the identification and characterization of 3000 year old (Iron Age) hydraulic plaster surfaces from the site of Tell es-Safi/Gath. This site, located in central Israel, was occupied almost continuously from prehistoric through modern times, and is identified as the Canaanite and Philistine city of Gath. A survey using an on-site Fourier transform infrared spectrometer (FTIR) identified the presence of amorphous silicates, in addition to calcite, in each of two superimposed plaster layers. This suite of minerals is characteristic of hydraulic plaster. An in-depth characterization of the plasters using FTIR, acid dissolution, X-ray fluorescence (XRF), X-ray powder diffractometry (pXRD), heating experiments and scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (SEM–EDS), shows that special silicate-containing minerals were brought from some distance to the site in order to produce these plaster surfaces. We therefore conclude that the plasters were deliberately produced, and were not the result of a fortuitous addition of local silicate minerals. A layer of around 150 μm thick enriched in carbonate hydroxylapatite was found in both plaster surfaces, and the same mineral was identified by infrared spectrometry in the surrounding sediments. This suggests that organic materials were used on these surfaces. These surfaces are among the oldest hydraulic plasters known.  相似文献

During the 18th century, back-bench members of parliament played a critical role in creating social policy. This article provides a case study of the political campaigns of the Lichfield MP, Thomas Gilbert, and his attempts at a comprehensive reform of the poor law in 1765 and 1782. These individual endeavours were energetic, sophisticated, but unallied to a particular agenda or based on Gilbert's original perspectives. Instead, he harnessed the power of local interests and extra-parliamentary forces, particularly magistrates, through the adept use of print culture in his later campaign to form social policy based on a broad political consensus. A skilled political operator, he used these same methods to help navigate his bills through parliament. To better fit the context, the campaigns were moulded around political expediency and influenced by the development of Gilbert's humanitarian reputation and the burgeoning of the press, parliamentary reporting, and political debate. The political environments of 1765 and 1782 were, therefore, different, and broader trends influenced the two campaigns. This article demonstrates the importance of the press to political campaigning and suggests that to be successful (in social policy at least) a would-be reformer was required to engage with a developing participatory political culture. However, given Gilbert's approach, the importance of ideology as a basis for social reform in an 18th-century context is questioned.  相似文献

A student raised a hand in class and asked, "Why is this dorm named after Alexander Graham Bell?" On a deaf campus, this was a loaded question. Bell was an oralist, opposed to sign language. He was a eugenicist, opposed to deaf marriages. Indeed, the more I thought about it, the better this question got. Why did the school name a dormin after him? Unfortunately, I hadn't the foggiest idea. With apologies to that student, I offer this article as a belated answer.  相似文献

Linear enamel hypoplasia is a physical deficiency occurring during the process of enamel formation and it is visible on the crowns of mammal teeth. It can be used to trace physical stresses during life. In this study, linear enamel hypoplasia in samples of pigs from three Neolithic sites in the Wei River valley (China) were recorded and analysed, to investigate the status of pigs at these sites, their living conditions, and furthermore to explore husbandry strategies for pigs during the Neolithic in the valley. The results suggest a domesticated status for pigs in the Neolithic and early Bronze Age. Also the frequency of LEH occurrence for the pigs corroborates a presumed intensification processes of pig husbandry, and the presence of environmental fluctuations during the period are considered. Some evidence also points to the fact that for pig, spring farrowing was the most common reproductive strategy in the Neolithic and early Bronze Age in this region.  相似文献
